BAILER.

Application filed November 30, 1907. Serial No. 404,577.

T all whom it may concern:

Be it known that 1, DAVID KnuiunL, a citizen of the United States,residing at 'Warren, in the county of Warren and State of Pennsylvania,have invented a new and useful Oil-Well Bailer, of which the followingis a specification.

The present invention relates more particularly to means for bailing oilor other liquid I from wells, and the primary object is to prol videnovel valve mechanism which can be readily applied to and detached fromthe body of the bailer without the necessity of dismembering the same,said mechanism bei ing provided with straining means which will preventthe ingress ofsand, slate, or other solid substances that mightinterfere with the proper operation of the valve.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a vertical sectional viewthrough the mechanism and through the lower portion of the bailer body.Fig. 2 is a horizontal sectional view on the line 22 of Fig. 1.

Similar reference numerals designate cor slponding parts in all thefigures of the L rawmgs.

The body of the bailer, designated by the reference numeral 3, istubular in form, and may be of any suitable construction. To its has anupstanding flange 5 fitted within the body and fastened thereto byrivets 6 or other suitable devices. This bottom mem ber has a centralthreaded opening 7. A casing 8 is employed that has a contractedupstanding neck 9, a portion of which is threaded and is screwed intothe opening 7 of the bottom member, as shown. This neck eX- tends intothe body and its upper end 10 constitutes a valve seat. The casing 8 hasan interior chamber 11 and its side walls are provided with a pluralityof inlet openings 12. The bottom 13 of the casing is also provided witha central 0 ening 14.

A valve 15 of eather or other suitable material cooperates with thevalve seat 10, and is secured to a vertical valve stem 16 that eX- tendsdownwardly through the casing and through the bottom opening 14. Thevalve 15 bears against a tapered abutment nut 17 that operates in theneck 9 of said casing, while a metallic washer 18 rests upon saidthreaded upon the upper end of the stem. The lower end of the valve stemcarries a closure disk or plate 20 located below the casing and movableupwardly to cover the opening 14 when the valve is open, as will beevident.

The main body of the casing is provided with two outstanding ribs 21that extend completely around it above and below the inlet openings 12.A screen 22 of any suitable material surrounds the body between the ribs21, and covers the inlet openings.

With this structure, it will be evident that when the bailer isintroduced into the well, the plate 20 striking the bottom of said well,will cause the upward movement of the stem 16 and the consequent openingof the valve. At the same time said plate will cover the opening 14 andprevent the inflow of fluid therethrough. Such fluid, however may flowfreely through the openings 12 into the chamber and passing upwardlythrough the casing 9 will enter the bailer body. Then the bailer israised, the valve will immedi ately close, and at the same time, theplate 20 will uncover the opening 14. There are decided advantages forthis structure. In the first lace, the casing with the valve, can beread y removed and replaced so that in case repairs or renewals arenecessary, the same can be made with ease and expedition. The straineras will be evident, prevents the ingress of solid particles ofsuflicient size to interfere with the proper working of the valve, andthis strainer is held in place and is protected by the upper and lowerribs 21 and 22, between which it is placed. The lower opening 14 and itsclosure 20, also are advantageous features, for while said opening isclosed during the inflow of oil or liquid, when the bailer is raised,the opening 14 being uncovered, whatever liquid remains in the easing,together with any sediment that may collect in the bottom thereof, canflow freely out through said opening 14.

From the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion and minordetails of construction, may be resorted to without departing from thespirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a structure of the character described, the combination with atubular body, of a casing depending therefrom and having lateral inletopenings and a bottom provided with an opening, a valve, a valve stemcarried. by the valve and extending through the bottom opening, and aclosure for the bottom opening carried by said stem.

2. In a structure of the character de scribed, the combination with atubular body, of a casing depending therefrom and having lateral inletopenings and a bottom provided with anopening, a valve, a valve stemcarried by the valve and extending through the bottom opening, and aclosure plate for the bottom opening carried by the lower end of thestem and located exteriorly of the casing, said plate covering thebottom opening when the valve is opened.

3. In a structure of the character described, the combination with atubular body, of a bottom member secured to the lower end thereof andhaving a threaded opening, a casing having an upstanding contracted neckthreaded into the opening, said neck terminating at its upper end in avalve seat, the casing furthermore having inlet openings in its sidewalls and having a bottom provided with an opening, a valve cooperatingwith the seat, a valve stem depending from the valve and extendingthrough the bottom opening, a closure for said bottom opening carried bythe lower end of the stem and located outside the casing, and a screencovering the inlet openings.

4. In a structure of the character set forth, the combination with atubular body, of a casing suspended from the body and having the wellduring the movement of the structure therein.

5. In a structure of the character set forth, the combination with atubular body, of a bottom member secured thereto and having a threadedopening, a casing comprising a chamber and a contracted neck, the latterbeing threaded into the opening and terminating at its upper end in avalve seat, said chamber having inlet openings in its side walls withribs extending around the outside of the chamber on opposite sides ofthe opening, the casing furthermore having a bottom provided with anopening, a valve cooperating with the valve seat, a stem depending fromthe valve and slidably passing through the bottom opening, a closurelate for said bottom openings carried by the lower ends of the stem, anda screen surrounding the body between the ribs and covering the inletopenings.

In testimony, that I claim the foregoing as my own, I have heretoaffiXed my signature in the presence of two witnesses.
